And was dissapointed.....my best was a 12.71 @ 111 with a 1.90 60 ft time. Car is an auto, bone stock with about 5K miles on it. OAT were about 85-90 and it was humid but I thought this car would do better then that!! The low trap speed is what concerns me the most...I thought these cars were trapping 117-120?? Whats up with that?? Am I that shitty of a driver or what?

Probably... But I have to ask... in your track times were U running it SPORT and Competition Modes??? Because it sounds like U were in NORMAL

The Tranny was in sport and the TC was switched to competition mode. Im going back next weekend (the 27th) and see if I can get it down a couple of tenths. The track was prepped well so I'm goin to try and take the TC all the way off and just drive it to see if I can get a lil bit better 60 ft time.....and heat soak was a problem, my first run I went though the traps @ 113.9

You would only ask this question if it were a 6 speed...

In Auto....you have to double tap tc off/ set suspension to sport and toggle the manual stick over to sport as well

these 3 functions make a world of difference. what octane were you using....trust me....100 octane is not wasted on this car.. the heat pulls timing...the octane give some timing back.

Ok worst case....its a 12.7 car.....you know how many cars wish stock they could run that....add a cold air , a tune more psi and 11's come quickly.


spray the engine down with n20 before staging....if waiting a long time...expect some eat soak.

If you were driving a stick....then i think you need practice... and the right fuel. No reson not to get 12 flat in auto out of this car with good gas and a Intake.

High humidity with those high temps is a perfect formula for less power output. I've seen cars lose a full second (1.0+) and 5-10 mph with those conditions.. and that's at Sea Level. Throw in some higher altitude in the mix and there isn't a lot of good air left.
Heat soak as others have mentioned is another culprit as well.
Try it again on a cooler day or Night and you'll see a big difference. :)

Guy's where the hell is the traction control button on the cts-v ?
Thanks -cadyshak
Cadyshak - Someone has already asked but I didn't see your response yet: Did you have the trans in sport mode (throw the stick to the right while in drive)? If you don't put the trans in sport mode the car will launch in second gear after the initial shift out of first which will probably occur as you're driving up to the line. If you put it in sport mode you don't have to shift manually - Just let it shift itself.

Heat soak probably deserves a thread unto itself...but I have inserted a 5.6 ohm resistor into the IAT sensor wiring in my SRT 10. It effectively fools the cpm. This lowers the temperature that is read by the cpm to avoid programmed pulling of timing due to high IAT...

Has anyone tried this with the CTS V?

no resistor mod please! use higher octane. .....definitly a meth kit should be made for this car.

the auto has been proven faster ..in stock form. You think you can outshift a computer?


You didn't give us all the varables....but i assure you 12 flat is doable in stock form. the TC double tap and modulation of the throttle make a big difference..

and the sport suspension makes for no hop launches..
My 04 GTO had drag springs and Koni's on the highest setting......the GTO was notorious for hop...it launched clean ... You might want to invest in better tires.. the rear is near bullet proof.


but temp/ alt/ and heatsoak / are a FI enemy still a 4300# caddy runny 12's aint all that bad... rolling racing
is more its thig..and its an overall performer... Its a perfect wheel car

Add a JB intake and tune and electric cutouts...it will screem
